I played it on Hard and many of the major battles would eventually devolve into a me-and-my-buddy or just me-the-lone-gunner situation simply because they'd all die. If Infinity can't improve the friendly AI, they might as well just increase their health. Perhaps this could be done everytime your allies attain a kill to reward your leading them into battle.
